Pointless "Set-Location/Set-LocationEx" auto-complete shows up when I start up a new session

I have a fairly complicated profile script, but PowerTab is currently the second-to-last command in it. However, whenever I start up PowerShell, I get a useless and annoying tab completion window that displays Set-Location and Set-LocationEx; I generally
have to type some gibberish, hit Tab, and then Esc a few times to get rid of it.

I've had the same problem and could workaround it by setting the Default Tab Item Selector to "Intellisense". You can do this by changing the value of the "DefaultHandler" property in the "Global" category to "Intellisense"
within the PowerTabConfig.xm file.

I have run into this as well. The problem is that PS v3 will automatically run a tab expand for "Set-Location" right after your first prompt comes up. I don't know why it does this and I am looking for a good way to detect this happening and
not show it to the user.
